3-way Trunnion Valves
Developed for high pressure, side-loading applications, the 316 stainless steel trunnion is supported and held securely in position by two composite bearings. Encapsulated Nylatron seats provide a positive seal, resulting in leak-tight sealing between all ports to 6000 psig differential, reducing operating torque and increasing cycle life. The handle points to the side port in use; when perpendicular to the side ports, it indicates the shutoff position.

Typical Applications
  • Compressed natural gas dispensing
  • Instrument air lines

    Features & Benefits

  • Blowout-proof stem for added safety
  • Trunnion design assures leak-tight sealing at full 6000 psig (414 bar) diff erential pressure for high pressure applications.
  • Handle points to port in use or to closed position, providing a visual cue and improved safety.
  • Encapsulated dual Nylatron seats and Viton stem seals ensure a leak tight seal. This combination provides greater valve reliability.
  • Special High Tolerance NPT Thread
